Invitation for Bid: DOFAW-KAWAIKINI-ALAKAʻI-26

I. Overview of Services Requested: Fence Construction for the Kawaikini and East Alakaʻi Summit Fences, Kauaʻi

Overview

The Division of Forestry and Wildlife (DOFAW), Department of Land and Natural Resources (DLNR), State of Hawaiʻi (State) plans to construct a protective ungulate-proof fence within the Kawaikini Preserve, in addition to repairs to a section of the East Alakaʻi Protective fence and removal of old materials. Both project sites are located on the Island of Kauaʻi on a mixture of private and public lands managed by the Kaua‘i Watershed Alliance (KWA).

Scope of Work

Research within the Hawaiian Islands has demonstrated that feral pigs, goats, and sheep, which damage native vegetation, expose soil to erosion, and can pose a significant threat to the native biodiversity and watershed integrity of Hawaiian forests. Decades of hooved animal control in Hawaiʻi verify that the only successful method of completely protecting an area is to exclude the animals with a fence.

The Kawaikini fence will protect and preserve approximately 785 acres in the Kawaikini Preserve from hooved animals. This proposed fenceline is approximately 4,699 linear feet (LF) or 1,432 meters (3 sections). See Exhibit A.

The East Alakaʻi Protective fence currently protects about 2,000 acres of priority watershed from hooved animals on the Alakaʻi Plateau but requires extensive repairs. The fence is approximately 2,360 LF or 719 meters (2 sections) and will involve the replacement and removal of old materials. Another highly degraded fence segment in the area, approximately 6,655 LF or 2,028 meters, will be required to be removed. See Exhibit B.

Please note that minor changes in the fence alignment may be made due to terrain or for avoidance of sensitive features, such as the identification of endangered plants and/or archaeological features.

East Alakaʻi TMKs: (4) 5-8-001:001 and (4) 4-2-001:002

This project area is located on the Alakaʻi Plateau. Most of the project area is in native-dominated ecosystems. The montane wet forest of this area is characterized by an ʻŌhiʻa-ʻOlapa canopy with the understory and open spaces dominated by a mixed assemblage of native sedges, grasses, herbs, shrubs, and ferns. The topography is irregular with meandering streamlets, ridges and gullies, and associated bogs. This project area extends to the summits of Kawaikini and Waiʻaleʻale mountains, which are both dominated by open bogs and windswept ridges with low stature, exposed vegetation.

II. Contractor and Crew Activities

Access to Installation Site The Kawaikini and East Alakaʻi project areas can only be accessed by helicopter. The western (makai) side of the Kawaikini project area has only one open bog to serve as a helicopter landing

OFFER FORM OF-3 Please Upload; Keep Original zone (LZ) (445804 x 2441021). At the eastern (mauka) side of that project area, containing the Kawaikini summit, there are numerous open areas to serve as LZs. The East Alakaʻi project area also has numerous open areas along the fence route which can serve as LZs, particularly near the summit where bogs dominate. The primary LZ is located along the fence (44770 x 2440787) at an elevation of 4,790 feet. Contractor camp sites are paired with the LZs. See Camps section below.

Weather conditions at the fence sites are at times extreme and may change rapidly. Therefore, the work activity is weather contingent, and the Contractor must have a flexible schedule and be able to respond when weather conditions allow access.

Biosecurity

The purpose of this project is to protect valuable watershed and native habitat with high conservation value. Plants or animals may not be removed from the fencing sites. The Contractor will implement precautions to prevent the introduction of alien plants, animals and insects. The Contractor shall be responsible for sanitizing all tools, equipment, fence materials, and gear before transporting to the work site. Boots, equipment and materials will be cleaned and inspected by the Contractor for seeds, soil, eggs, larvae, etc. All camping equipment and personal belongings must be inspected and/or treated to prevent the transmission of Rapid ʻŌhiʻa Death (ROD), Little Fire Ants, Coqui frogs, Coconut Rhinoceros Beetle (CRB), and other pests.

The Contractor will also take precautions to prevent spreading alien plants already found at the fencing sites. If arriving from other islands, the Contractor must perform these tasks prior to transporting equipment and personal gear to Kauaʻi. The Contractor will not store materials prior to material drops in areas known to contain ROD, Little Fire Ants, CRB, etc. The Contract Administrator reserves the right to inspect all gear prior to deployment to ensure cleanliness. The Contractor will remove all food, refuse (including human feces), tools, gear, and installation scrap at all stages of the fence installation and upon completion of work. Extra fence material may be left at the site, panels discreetly attached upright to existing fence, T-posts bundled on the inside of fence area, skirting on the inside of fenced area, and all excess material should be stored away from fissures, streams, bogs, or exposed ridge tops.

Site Preparation The Contractor shall be responsible for clearing (brushing) a fence corridor, fence construction, and post-construction clean-up. The Contractor shall be responsible for brushing (removing) some vegetation on either side of the final or corrected fence alignment (no more than ten feet total) as the fence shall be constructed at or near the midpoint of the clearing. All stumps shall be removed or cut to a height and distance sufficient to prevent any pig, goat, or deer from using them to climb up, reach the top of the metal fence, and either force or chew through the plastic deer‑mesh extension. The Contractor should minimize clearing wherever possible to reduce impacts to native vegetation. Additionally, the contractor shall be responsible for removal of

OFFER FORM OF-4 Please Upload; Keep Original standing dead trees (snags) even when just outside the brushed corridor, if they could pose a serious future threat to the fence when falling. Note that it is not necessary to remove all vegetation, but unstable limbs which are damaged, dying, dead or rotting should not overhang the constructed fence since they have a greater chance of falling onto the fence in the future.

Brushing of plants along the fence corridor should only remove those plants that may hinder fence construction, future fence inspections, or pose a future risk to the fence, and cut debris should be placed in designated areas to avoid any conflicts with fence maintenance or endangered species in the area.

Endangered species may not be cleared or disturbed and will be flagged with pink and black striped flagging by the State. The entire fence line is within endangered species habitat and thus, extreme caution must be used during clearing and installation of all phases of the fence line. The State and the KWA have conducted biological surveys and have flagged all known rare species locations and have routed the proposed fence line to avoid these resources. However, there may be times when the fence route runs unavoidably close to rare species and the Contractor will be responsible for not damaging those resources.

In addition, large healthy native trees shall be avoided as much as possible. Should ‘ōhi‘a trees need to be limbed, the open wounds should be treated with latex paint (or a similarly approved product) within a maximum of 10 minutes of cutting to minimize risk of exposure to Ceratocystis (ROD) or other pathogens and discourage beetle infestation.

There are no known archaeological sites within the fencing corridor, but if found they will be flagged and must be avoided. If the Contractor finds bones or cultural artifacts at any time during site preparation or installation, work must immediately cease and DOFAW must be notified immediately.

Kawaikini

The fence corridors have been delineated and flagged. It is recognized that for installation purposes, the Contractor may choose to shift the flagged alignment slightly. The fence alignment may need adjusting prior to and/or during corridor clearing, and only after consultation with DOFAW and KWA staff. Upon approval, the Contractor may re-align the fence to straighten alignments, to adjust corners, to avoid certain trees and shrubs, to avoid any rare plants or nesting birds, and to avoid potential archaeological structures.

East Alakaʻi

The existing fence line location will be maintained, so no new fence routes are needed. Because there is already an existing fence route, and the site is very open and boggy, minimal clearing of vegetation is anticipated. However, for installation purposes the contractor may choose to shift the existing fence alignment slightly. This may occur only after consultation with DOFAW and KWA staff. Upon approval, the Contractor may re-align the fence.

Due to the deteriorated condition and high conservation value of the summit fence, the State strongly encourages the Contractor to prioritize replacement of the East Alakaʻi summit fence

OFFER FORM OF-5 Please Upload; Keep Original whenever weather, logistics, and helicopter access permit. The sequence of work shall otherwise remain at the Contractor's discretion unless directed by the Contract Administrator.

Camps

Camps will be paired with LZs at designated locations in the general project area. There are three designated camp sites within the Kawaikini/East Alaka‘i project area. There is no existing infrastructure at any of these sites. The Contractor will be responsible for supplying their own temporary camp infrastructure and removing all trash and materials upon completion of the project. If there are questions or if additional sites are desired, DOFAW/KWA staff will coordinate with the Contractor on appropriate camping locations.

The camp site for the main western section of the Kawaikini Fence is about 2,162 feet (659 meters) from the fence within an open bog. The camp site for the small SE wing sections of the Kawaikini Fence is 165 ft (50 meters) from the fence sections. Conditions are very wet and windy there, but the Contractor should not need to camp at the summit for long. See Exhibit A.

The camp site for the East Alaka‘i fence is about 2,083 feet (635 meters) from the western start of the fence replacement section. Conditions are very wet and windy so a low-profile camp such as a lean-to is recommended here. At this site, the LZ is located on the outside of the existing fence and the camp is located on the inside where it’s more protected and there is a small stream.

Because of this, the Contractor will install a gate at the LZ to allow them to cross over easily. See Exhibit B.

Equipment, Supplies, Transportation, and Labor The Contractor shall be responsible for the provision of the necessary installation equipment, supplies, tools, and all labor required to install fencing as specified herein. The Contractor shall be responsible for transporting all required fence materials from the staging area to the installation site. The Contractor shall be responsible to provide their own transportation of all materials, work crews, equipment, and supplies to the installation site. The Contractor is advised that DOFAW shall not supply personal protective equipment (PPE) or communications equipment (i.e. helicopter radio).

DOFAW will not provide any helicopter transport for the Contractor’s crew or material. The Contractor shall coordinate its work schedules, timing and other relevant communications directly with the Helicopter Contractor; however, DOFAW/KWA shall be notified at least 5 days in advance of proposed work and flight schedules and included in pertinent communications affecting the project. The Contractor must obtain all necessary landing permits prior to commencing work. All permits must include a schedule of work and list the Contractor’s staff working on the project at the time. The Contractor will work with the Contract Administrator to identify appropriate helicopter landing zones if sites outside the pre-designated LZs are requested.

OFFER FORM OF-6 Please Upload; Keep Original

Fence materials will be staged on the west side of Kauai where the Contractor can access them to assemble sling loads and send the materials directly up to the installation site from there. Please review the biosecurity portion of this contract and check materials thoroughly for invasive pests or weeds before sending materials to the installation site. Additional materials may be available for pickup at the DOFAW baseyard in Līhuʻe. The Contractor may not use the DOFAW baseyard as an office or staging area; for storage of tools, supplies, equipment, or other materials;

or for overnight vehicle parking.

Communication DOFAW recognizes that the Contractor may not work on the job continuously from start to finish. At the same time, DOFAW has management responsibilities that must be coordinated around the fence installation schedule. Thus, the Contractor shall notify DOFAW/KWA at least five (5) days in advance whenever work at the Project site is planned to begin and shall notify DOFAW within three (3) days of leaving the Project site if the Contractor plans to be away for more than one (1) week. All camping and landing permits required for any camping and landing to be conducted on State land must be acquired from the local DOFAW office prior to the commencement of work. For private land access, the Contractor shall coordinate with KWA staff to complete and submit staff waivers.

Project Completion Upon completion, surplus materials that have been staged at the installation site will be arranged neatly along the fence route for use in future repairs. Surplus materials left at the staging site will be transported to a material depot identified by DOFAW. The Contractor will remove all scrap pieces (e.g., bits of wire mesh, smooth wire, damaged posts, and discarded spades), tools, and trash from both the project site and the staging site.

III. Fence and Materials Specifications

Fence Materials DOFAW has purchased the fence materials and will provide the Contractor with the materials as listed below. Despite shipping delays, most of the fence materials should be available before October 2026. Please contact DLNR with any questions or concerns. The Contractor shall ensure that the State DLNR shall get the benefit of all applicable manufacturer’s warranties; and all fence materials shall remain as the property of the State. If the contractor seeks to use materials in addition to or to replace the listed materials (at their own cost), the Contractor must submit in writing a list of their proposed materials at least 14 days before bid opening. These must be of the same or higher quality to complete fence installation. DOFAW will issue an addendum prior

The following specifications are necessary to ensure the fence prevents feral ungulates from entering the area enclosed by the fence and to minimize long-term maintenance.

OFFER FORM OF-9 Please Upload; Keep Original

Fence Posts (T-Posts)

T-posts are used as fence posts to support the fence. Schedule 40 pipe can be used as fence posts in areas where additional bracing is needed (see bracing section below). Standing trees or snags may not be used as fence posts.

Fence posts of all lengths will be spaced no more than 8 feet apart (in the middle and at the ends of each panel) and closer when terrain dictates. Each panel connection will have a post supporting it. T-posts shall be driven perpendicular to the slope of the terrain so that the height of the fence is not compromised over steep terrain sections. String and level will be used to keep posts on center and plumb. At each panel change in angle of the fence line greater than 30 degrees, 3 posts shall be used to create the corner. One post shall be driven at the vertex of the angle and two posts shall be driven at least 4 feet from either side of the vertex post.

T-posts shall be driven to a minimum depth of 24” or 36”, as specified within the following sections. If a post is not stable at a depth of two feet; the post will be pounded down until secure and a second post will be sunk two feet into the ground and secured to the first post. Posts shall be driven into the ground to withstand 75 pounds vertical pull and any horizontal force that would cause the posts to be uprooted prior to being bent. T-posts shall be driven by use of a tubular post driver or driving cap in a manner that will prevent damage to the T-post; a Post-mate type driver that attaches around the T-post may also be used.

Fence Panels

Fence panels will be hot dipped galvanized 52” by 16-foot combination panels, with graduated spacing and up to 13 horizontal bars. Panels will be attached to pounded T-posts using 9-gauge smooth wire. At each T-post the panel shall be attached at a minimum of 4 places; one along the top horizontal, one along the bottom horizontal, and two places evenly spaced in between. Any sharp tag ends of wire or tines must be bent inwards as to not pose a hazard to passersby.

Livestock panels shall be flush along the ground. In situations where the ground is uneven, the ground must first be graded to accommodate the fence panel. In event that grading is not enough, fence panels can be cut to accommodate the shape of the terrain. Successive panels shall be attached using hog rings. When attaching two successive panels, a minimum overlap of two columns of squares must occur to ensure that flex in the fence is minimized. Adjoining panels must also align and be hog-ringed along the vertical (not the horizontal) axis. Securing adjoining panels on the horizontal axis will cause the adjoining panels to slide apart when pressure is applied at that spot in the fence; this sliding apart of adjoining panels is unacceptable. Securing adjoining panels along overlapping vertical axes is the only way to avoid slippage between adjacent panels and is the only acceptable method for connecting panels. A minimum of 8 hog rings shall be used to connect adjoining panels; 1 shall be used at each of the 4 corners where the two panels overlap, and the other 4 shall be used at additional areas as needed. Panels may be bent to accommodate slight changes in angle of the fence line. However, when sharp angles are encountered (60 degrees or more) panels should be cut and opposing verticals of the two panels should be interlaced and bent back on themselves.

OFFER FORM OF-10 Please Upload; Keep Original

Ties

Ties of 9-gauge galvanized steel smooth wire shall be twisted around posts, wire, and fence panels only tight enough to be secure. Overtightening to the extent of damaging the fencing materials will not be allowed. Ties should be tightened so they are not loose and there is no play between the tie and the T-post. Fence panels shall be attached to the T-posts at four points: the top and the bottom of the panel with two ties evenly spaced in between the top and the bottom.

All tie ends must be bent inwards so as to not pose a hazard to passersby. The Contractor will be supplied with rolls of wire that they can cut to size for making custom ties.

Apron

Apron shall be continuous, of either 32-inch high tensile steel woven Bezinal coated fencing wire fabric, or 36-inch wide 2” x 4” mesh horse panel in boggy areas. The wire apron shall be attached directly to the lowest accessible eye of the fence panel and the fence wire shall be stretched horizontally over the ground on the outside of the fence. The side of the wire apron with the smallest eye must be the side connected to the bottom of the fence panel and the apron shall be attached to the panel fence using 9-gauge hog rings no more than every 12 inches apart.

The apron mesh shall be secured to the ground using arrowhead-style earth anchors attached to the wire and driven into the ground. Anchors shall be spaced no more than 15 feet apart.

Additional anchors may be required to attach the apron securely to the ground.

The bottom apron will be on the ground surface, or no more than 2 inches above the ground surface. Ground surface is the actual soil surface and not the vegetation mat. The vegetation mat and soil shall be removed manually along the fence line as required, to allow proper installation of the fence and apron.

Where obstacles such as rocks or large roots appear, either these items must be removed, or the skirt must be installed to fit tightly around these surface irregularities. Where the skirt is cut to accommodate objects, or at the apron-wire rolls’ ends, the strands of wire must be bent down and secured into the ground to avoid injury of hikers and hunting dogs.

For the sections where horse panel grate is required, the panels will be cut to size to match the terrain. The apron panel shall match up to the base of the panel fencing and be secure to the bottom line with 9-gauge hog rings no more than every 12 inches apart. Earth anchors should be spaced no more than 15 feet apart. Where the apron wire and the horse panel meet, they must be overlapped and secured using hog rings and the loose wire ends cut off or bent down to avoid injury of hikers and hunting dogs.

Hog Rings

Hog rings (9-gauge) shall be used to secure the apron to the bottom of the panel fence as described in the apron section above. They will also be used to secure the connections between fence panels, as described in the fence panels section above. Hog rings (12.5-gauge) will be used to secure deer mesh to the top wire and the fence panels. When attaching apron, deer mesh or

OFFER FORM OF-11 Please Upload; Keep Original fence wire to panels, hog rings will be a minimum of 12” apart, or less as described in other sections.

Top Layer of Fence

Most fences in this contract must be built to a height of 8-feet (except for the 225-foot Blue Hole natural barrier). For the Olokele section of the Kawaikini fences, this top layer will be deer mesh which will overlap the stretched fence wire or livestock panel at a minimum of 20 inches and no more than 30 inches. One strand of high-tensile galvanized steel smooth wire at the top of T-post (at 8’) will support the deer mesh. The deer mesh will be secured to the fence wire or panel with 12.5-gauge hog rings and to the top strand wire (8 feet high) at 8-inch intervals.

For the three summit fence sections, the top layer will be stretched ungraduated sheep/goat wire attached to the bottom fence panel with 9-gauge hog rings. Woven wire shall not be deformed to adapt to variations in contour. “Bellying” is unacceptable.

Bracing

High winds occur frequently at the mountain summits, so these fences must be well braced to ensure stability and to stretch the wire fence. Braces will be Schedule 40 pipe (S40) built in a “N-brace” style. Where bracing is needed, a 2 ⅜” x 10.5-foot S40 will be driven 2.5 feet into the ground for an above-ground height of 8 feet. A 2 ⅜” x 4-foot S40 will be driven 2’ into the ground and a 2 ⅜” x 8-foot S40 will connect the two posts on the diagonal. Arrow brackets will connect the diagonal pipes. Caps will be attached to seal the tops of the posts. See Exhibit E.

The entire Kawaikini summit sections and two portions of the East Alakai summit fence totaling 720 feet (219 meters) will require double bracing. In these sections, the fence must be braced on both sides and at a minimum frequency of every 40’. The fence must be stable, and more frequent braces may be necessary to ensure stability of the fence.

In the rest of the East Alaka‘i replacement fence area (1,654 feet, 504 meters) braces must occur at a minimum spacing of every 80’ and will be place on just the Northern side of the fence.

However, the fence must be stable and more frequent braces or additional braces on the Southern side of the fence may be necessary to ensure stability. See Exhibit B.

Kawaikini Fence Installation – Minimum Specifications General

A 96-inch-high (8’) fence will be constructed using rigid livestock panel and either sheep/goat wire mesh or plastic deer mesh supported by galvanized steel pipes and/or metal fence posts. The outside of the fence will be continuously skirted along the base. Where the fence follows a trail, the Contractor will be responsible for building it in such a way that it does not block access for land managers (i.e., continuously situated on one side of the trail or another). Gates will be

OFFER FORM OF-12 Please Upload; Keep Original installed at strategic locations to allow access to intersecting trails and to allow land managers to cross the fence easily for regular inspections and maintenance.

The Kawaikini Fence project is 3 individual fences. There is one long section along the western edge of the unit that is approximately 4,429 feet ( 1,350 meters) in length. This will be referred to as the Olokele section. There are also two smaller sections on the southeast end of the unit that are 239 feet (73 meters) combined. These are referred to as the Kawaikini Summit sections.

Build specifications for these two sections are different and those differences are described below. See Exhibits A and C.

Olokele Section

The longer Olokele section (4,429 feet) will be constructed with 10’ T-posts driven 2’ into the ground to a height of 8’ and spaced no more than 8’ apart. Graduated 16’ livestock panels will be attached to the T-posts using 9-gauge smooth wire ties. A high-tensile carbon steel wire will be strung along the top of the T-posts. Deer mesh will be attached with 12.5-gauge hog rings to the top wire and the fence panels. Flexible wire mesh apron will be attached to the bottom of the fence with 9-gauge hog rings and secured to the ground with earth anchors. Five gates will be installed along the fence.

There is one stream crossing along this fence route, but since it cliffs out to a waterfall, a stream curtain is not required. At its southern end, the fence terminates at a cliff. The Contractor will extend the fence over the edge of the cliff to prevent animals from walking around the end of the fence. At the northern end, this fence will intersect with the existing Halehāhā protective fence.

Kawaikini Summit Section

The Kawaikini summit section has two short wing fences, one that is 216 feet and another that is 23 feet. Both ends of both fences will be tied into natural barriers. For the longer fence, both ends must overhang cliffs that drop away. For the shorter section, one end ties into the base of one cliff face and the other end will overhang another cliff below. The Contractor must construct these ends so that animals cannot walk around the ends of the fences. Panels must extend past cliff edges and must be cut to fit the base of cliffs with a gap of 4” or less.

The Kawaikini summit fences will be constructed from livestock panel lower portion supported by 12-foot T-posts driven 3-4 feet into the ground and extending 8-9 feet up. T-posts will occur every 8 feet along the length of the fence. Every 40 feet a 2 ⅜” x 10.5’ Schedule 40 pipe will be used as a fence post and it will be braced on both sides in the “N-brace” style with more S40 pipe and connectors. These braces will also be used to stretch the sheep/goat wire for the top layer of the fence. The wire will be secured with smooth wire ties and connected to the lower fence panels with 9-gauge hog rings. There will be an apron attached to the outside of the fence with 9-gauge hog rings.

East Alakaʻi Fence Removal – Minimum Specifications General

Three fences exist in the East Alaka‘i Summit project area. The first fence, originally built to protect the Wai‘ale‘ale summit bog, was constructed in the 1990s of 6-foot T-posts and hog wire and it is highly degraded. The second fence is the main East Alaka‘i Protective Fence, built in 2011 to protect approximately 2,000 acres of bog and montane wet forest on the Alakaʻi Plateau and it fully encompasses the original summit bog fence. This fence was first constructed of a combination of graduated woven wire and combination livestock panel with 6-foot T-posts, schedule 40 corner posts and bracing. A retrofit to add deer mesh, with 10-foot T-posts and high-tensile top wire, was completed in 2021. A combination of solarization and high-winds have damaged the deer mesh and it has been patched in various locations with elk mesh, wire mesh, and various bracing materials. See Exhibit E. The wire mesh is also highly degraded by rust and the entire fence is falling over in places due to a combination of high winds and ground instability (soft mud). The third fence (or technically a segment) is the Blue Hole natural barrier fence which is simply 4-foot livestock panel and 6-foot T-posts with no top extension and no apron. This fence extends from the end of the previously mentioned 8-foot fence, down the steep cliffs of Kauai’s Eastern Pali and terminating at a natural barrier. The second and third fences will be removed in sections in tandem with replacement to ensure the fence remains animal-proof throughout the duration of the contracted work. The first section is strictly removal; no new fence will be constructed there.

Disassembly and Staging

T-posts will be pulled and secured into loads to be flown out by helicopter. All 6-foot T-posts throughout the project area are more than 10 years old; they are very rusty, and they will all be pulled for removal. The 10-foot T-posts along the main East Alaka‘i summit fence were all installed in 2021 and they may either be left in place to provide additional support to the new fence or removed entirely. However, they must be stable, and it is the Contractor’s responsibility to replace or reset any loose 10-foot T-posts.

Degraded fencing wire will be collected and gathered into a sling bag (or other enclosed container) for helicopter removal. Livestock paneling will be stacked and strapped together into loads for helicopter sling removal.

Deer mesh, elk mesh, and other non-metal fence materials will be collected and gathered into a sling bag for helicopter removal. Different materials (i.e. plastic vs metal) must be separated for appropriate disposal (trash vs. recycle).

Disposal

The Contractor will be responsible for removing materials from the site and proper disposal.

Proper disposal involves: 1) recycling metal fence materials at Puhi Metals Recycling Facility/Reynolds Recycling; 2) cutting plastic mesh into < 3’ segments and disposing at a

Kauaʻi County Refuse Transfer Station. Disposal loads may be staged at the Līhue DOFAW baseyard, or at the site on the West side where the materials will be staged.

Salvage and Reuse of Materials

All fence materials removed under this contract remain the property of the State. To reduce landfill burden, the State may, at its discretion, direct that usable materials (including intact steel T‑posts) be salvaged for reuse or donation rather than recycled or disposed, provided such reuse is authorized in writing by the State’s project manager. No removed materials may be appropriated for personal use, resale, or other non‑authorized purposes by the Contractor, and salvage or reuse shall not constitute additional compensation or create a bid advantage.

Fence Closure

The Contractor must build the new fence as they are removing the old East Alakai Protective Fence to ensure that the fence remains animal proof to a height of 48 inches. At the end of each workday, the Contractor must secure any open sections of fence with appropriate fencing materials (i.e. deer mesh or woven wire mesh). KWA staff will continue to monitor animal activity throughout the contract period. The Contractor shall notify KWA of any identified ingress or observed animal activity within the project area. The old Wai‘ale‘ale summit fence is strictly removal and does not require replacement or animal proofing.

East Alakaʻi Fence Installation – Minimum Specifications General

Along the main East Alaka‘i summit fence section (2,135 ft), a 96-inch-high (8’) fence will be constructed using rigid livestock panel and sheep/goat wire mesh supported by galvanized steel pipes and/or metal fence posts. The outside of the fence will be continuously skirted along the base. Where the fence follows a trail, the Contractor will be responsible for building it in such a way that it does not block access for land managers (i.e., continuously situated on one side of the trail or another). Gates will be installed at strategic locations to allow access to intersecting trails and to allow land managers to cross the fence easily for regular inspections and maintenance.

Bracing

The Wai‘ale‘ale Summit area is extremely windy and requires bracing with Schedule 40 pipes to ensure stability. Braces will be built in a “N-brace” style where a 2 ⅜” x 10.5-foot S40 will be driven 2.5 feet into the ground for an above-ground height of 8 feet. A 2 ⅜” x 4-foot S40 will be driven 2’ into the ground and a 2 ⅜” x 8-foot S40 will connect the two posts on the diagonal.

Arrow brackets will connect the diagonal pipes. Caps will be attached to the tops of the posts.

See Exhibit E.

OFFER FORM OF-15 Please Upload; Keep Original

Two portions of the East Alakai summit fence totaling 720 feet (219 meters) will require double bracing. In these sections, the fence must be braced on both sides and at a minimum frequency of every 40’. The fence must be stable, and more frequent braces may be necessary to ensure stability of the fence. Along the rest of the East Alaka‘i replacement fence area (1,654 feet, 504 meters) braces must occur at a minimum spacing of every 80’ and will be place on just the Northern side of the fence. However, the fence must be stable and more frequent braces or additional braces on the Southern side of the fence may be necessary to ensure stability. See Exhibit B.

Skirting

The Wai‘ale‘ale Summit area is very muddy with some deep mud pits along the fence route that make regular checks and maintenance difficult. In areas with deep mud a 36-inch wide 2” x 4” mesh horse panel will be used to span the mud pits and provide structure for maintenance crews to access the fence at these sites. Horse panel will be required along 427 linear feet of fence and it must be cut to size to match the terrain. Along the other 1,708 linear feet of fencing, a 32-inch high tensile steel woven Bezinal coated woven wire fabric will be used for fence skirting. Where the woven wire and the horse panel meet, they must be overlapped and secured using hog rings and the loose wire ends cut off or bent down to avoid injury of hikers and hunting dogs.

In all cases, the skirt shall be attached directly to the lowest accessible eye of the fence panel using 9-guage hog rings no more than every 12 inches apart and the wire shall be stretched horizontally over the ground on the outside of the fence. The skirt shall be secured to the ground using arrowhead-style earth anchors attached to the wire and driven into the ground. Anchors shall be spaced no more than 15 feet apart. Additional anchors may be required to attach the apron securely to the ground.

Where obstacles such as rocks or large roots appear, either these items must be removed, or the skirt must be installed to fit tightly around these surface irregularities. Where the skirt is cut to accommodate objects, or at the wire roll ends, the strands of wire must be bent down and secured into the ground to avoid injury of hikers and hunting dogs.

Gates

Within the main fence, there are two gates that the Contractor must install. Near the natural barrier, there is a dog stepover that will be removed and replaced with a step-through gate. At the Contractor’s camp/LZ site, they will add another gate to the existing fence allowing them to cross from the LZ to the campsite. There is one additional gate within the replacement area that can be reused and installed into the new fence at the same location. Both ends of this fence will connect into other fences, creating one continuous line. See Exhibit E for photographs of current site conditions at the East Alaka‘i summit fence.

Natural Barrier

Along the Blue Hole natural barrier fence (225 ft), a 48” (4-foot) high fence will be constructed using rigid livestock panel and 6-foot T-posts driven 2’ into the ground. There will be no top

OFFER FORM OF-16 Please Upload; Keep Original extension or skirt on this fence section. This fence terminates at a cliff where panels must overhang to prevent animals from walking around the fence. On the other end, it must connect into the main summit fence such that deer cannot jump over the short section into the unit.
